TL;DR
This paper explores the overall spacetime structure resulting from the collision of two AdS-filled bubbles formed via false vacuum decay, providing insights into the global geometry of such braneworld scenarios.
Contribution
It offers a detailed analysis of the global spacetime structure in colliding bubble braneworld models, a novel examination of their geometric and physical properties.
Findings
Characterization of the global spacetime structure after bubble collision
Insights into the geometry of AdS bubble interactions
Implications for braneworld cosmology and quantum tunnelling
Abstract
We comment on the global structure of the spacetime that results from the collision of two bubbles filled with AdS space produced from the decay of a false vacuum through quantum tunnelling.
